Carlsons 04505 Magazine Extension 12 Gauge 8-Shot Blued Steel - Fits Winchester SX2, SX3, SX4 & Browning Gold/Silver

The Carlsons 04505 Magazine Extension brings your 12 Gauge semi-auto shotgun up to an 8-shot capacity. Designed specifically for the Winchester SX2, SX3, and SX4, the extension is also a direct fit on the Browning Gold and Browning Silver family, making it a popular upgrade for hunting, sport shooting, competition shooting, home protection, and law enforcement use.

The extension tube is constructed from solid blued steel for durability and a factory-matching appearance. The threaded tube replaces the factory magazine cap, and the included spring, base clamp, and swivel stud make installation straightforward while providing a built-in sling attachment point. The blued finish blends cleanly with factory Winchester and Browning components.

Backed by the Carlsons Choke Tubes reputation for well-fitting shotgun components, the 04505 is a proven way to expand the practical capacity of your 12 Gauge semi-auto without modifying the action or magazine tube.
